Abstract

A series of iodine derivatives of ferrocenylphosphorus compounds has been obtained. An X-ray investigation of [Fc 3PI] +I 3 − has been carried out. All ferrocenyl fragments posses close geometric parameters, similar to those of ferrocene and its derivatives. The positive charge of the cation is localized on the phosphorus atom. Symmetrical I 3 − anions of linear configuration form zigzag-shaped chains, as is usual for triiodides. The cation—anion interaction is realized through short I…I contacts.
